So there is a Korean monk who cannot make a difference between the Buddha's teachings and those who believe in an ultimate self. Perhaps they should strengthen their studies of actual Buddhist doctrines instead of spreading incorrect views.
"There is no such thing as the real mind. Ridding yourself of delusion: that's the real mind."
(Sheng-yen: Getting the Buddha Mind, p 73)
“Don’t rashly seek the true Buddha;
True Buddha can’t be found.
Does marvelous nature and spirit
Need tempering or refinement?
Mind is this mind carefree;
This face, the face at birth."
(Nanyue Mingzan: Enjoying the Way, tr. Jeff Shore; T51n2076, p461b24-26)
